Is CVE-2026-103506 exploited?

No exploitation is reported in the sources VulniPulse tracks: CVE-2026-103506 is not in the CISA KEV catalog (checked Nov 5, 2026) and no tracked advisory for it reports exploitation. That is not proof the vulnerability cannot be exploited.

How do I fix CVE-2026-103506?

Upgrade to a fixed release named by the vendor:

Red Hat: grafana13-1-main-13.1.8-0.5.hum1, grafana12-4-main-12.4.13-0.5.hum1, RHSA-2026:91292

Ensure the experimental `kubernetesSsoSettingsApi` feature toggle is disabled. By default, this feature toggle is inactive. If this feature was manually activated, remove `kubernetesSsoSettingsApi` from the `[feature_toggles]` section in the Grafana configuration file (`grafana.ini`) or from the `GF_FEATURE_TOGGLES_ENABLE` environment variable. Apply the configuration by restarting the service: ``` systemctl restart grafana-server ``` Warning: Restarting the `grafana-server` service will result in a temporary interruption of service for connected users. Additionally, if the toggle was previously enabled, immediately rotate all associated SSO client secrets to prevent unauthorized access from potentially exposed credentials. (Red Hat)
